RADIATOR Patented Feb. 21, 1922.

Application filed'Jnne 16, 1919. Serial No. 304,516.

- the invent-ion has for its object to generally improve and simplify this type of radiator by the provision and utilization of a novel type of yertical water tube constructed of sheet metal and provided with a series of fins for increasing the heat radiating surface of the tube and causing the rapid coolingof the liquid passing therethrough.

Another object is the provision of a novel type of coupling connecting the terminals of the tubeswith the upperand lower water containing elements of the radiator whereby the tubes maybe quickly and convenlently removed for repair or replacement, and in case of emergency.

With these and other objects in view as will appear as the description proceeds the invention comprises the novel features of construction, combination of elements, and arrangement of parts which will be more fully described in the following specificatlon as set forth with particularity in the claims appended hereto.

Figure 1 represents a vertical central sectional View through the improved radiator. Figure 2 represents a plan view of one terminal of one of the water tubes and the clamping plate therefor, the same being removed from the radiator.

Figure 3 represents a fragmental longitudinal sectional view through the terminal of one'of the tubes.

Figure 4: is a transverse sectional vlew through the tube taken at right angles to Figure 3, and, V

Figure 5 represents a fragmentary perspective view of one of the nut retaining plates of the radiator structure.

Referring to the drawings in deta1l, wherein similar reference characters designate corresponding parts throughout ftl1e several views, the numerals 5 and 6 indicate generally the upper and lower members of the radiator which are of hollow formation 7 providing the internal water chambers for to be utilized in cooling the explosive engine (not shown) in'connection with which the radiator is used. The lower member 6 s formed centrally with an aperture communicating with a discharge coupling 7 whlch 1s adapted for connection with a hose or other hollow member whereby the cooled water is conducted from the lower portion of the radiator back to thewater jacket of the engine. The lower hollow member 6 is preferably constructed of two strips of sheet metal substantially L-shaped in cross section and: having the adjacent edges interlocked as indicated at 8 and soldered or otherwise connected so as to form a rigid and "fluid tight joint preventing leakage of the liquid contents of the member andmaintaining the member in proper form.

The upper member 5 is preferably constructed .of a plurality of strips of sheet metal having the adjacent edges interlocked as indicated at 9 and provided in the rear wall thereof with an aperture communicating with a coupling 10 adapted for connection with a hose or other hollow member whereby the heated water from the water jacket of the explosive engine is conducted to the upper portion of the radiator. The opposite extremities of the upper and lower members 5 and 6 are connected by the vertically disposed side members 11 maintaining the top and bottom members in properly spaced relation and increasing the strength and rigidly of the entire radiator structure. The top member is further provided with a filling spout 12 carrying a removable top 13. The top and bottom members are connected, intermediate the side members 11, by a series of vertical water tubes designated generally by the numerals 1 1 and each of which is constructed of a single piece of sheet metal doubled along a longitudinal line as indicated at 15 and having the longitudinal edges interlocked as indicated at 16 and soldered or otherwise secured together to render the joint fluid tight. As will be understood, the side members of the tubes are arranged in spaced relation to provide a water passage. The opposite terminals of each tube are flanged as indicated at 17 to engage the bottom of the top member 5 and the top portion of the bottom member 6.

Clamping or coupling plates 18- having elongated openings are movably engaged upon the opposite terminals of each tube 14 4%.... ii -atured to receive bolts 19 which extend the latter in engagement. with-the; top and through the upper and lower members 5 and 6 and are engaged with bars 20 wherebythe clamping plates-are brought in clamping I wally-increase the strength and-rigid ity relation with the flanges 17 to snugly clamp bottom radiator members and establish a fluid tight connection therewith. The top and-bottom members 5 and 6 are'provided with a seriesmofapertures registering with" the tubes '14: permitting a free circulation of liquid -;between .the hollow, members and tubes, [and flanges 21 are preferably; formed at the'edges ofthe openings in the top and bottom. members to strengthen and reinforce the radiatorstructure. V v

,Angular covering members 22 are secured in any suitable manner1internallyof the upper and lower members 5-and 6, to protect the barsfrom the water and prevent them from rusting and being otherwise deteriorated." The intermediate portionof each water tube is formed with staggeredly arranged and reversely corrugated portions 23 providing V a zigzag passage throughout the major portion of the length of thetube to' increase the,

heat radiating surface thereof and accelerate the cooling of the liquid passing therethrough. To further increase the ,cooling efficiency of the radiator each tube is preferably provided with aseries of parallel fins 24 projeeting laterally of the opposed side walls thereof, the fins onone sideof thetube being arranged in staggered rela- Ltion to those of the opposite side. -"The bars 20, being arranged internallyv of theup'per and lower members 5 and 6, mateof the entire radiator structure, and by the utilization of the angular retainingstrips 22 the bars are notonly held in adjusted position but are; alsore'spectively protected against the rusting andg corrosive action-of the cooling liquid contained within the radiator.
